    Have any members installed a real LSD in the rear of their RWD 2nd generation Tundra?
    What did you use, and how did it work out?

    I am looking at an Auburn unit, Thanks

    YOU WILL LOVE IT!!

    I also went with the 4:88 Gears as well front and rear Diffs since I'm on 20" wheels and 37" tires.

    That Auburn LSD is the shit!

    I won't be changing gears, so what else needs to be changed when the LSD is installed?

    Nothing else except they add new diff oil when they do the swap. Ive never had one wheel spin, always hooks up. Moved to Alaska last Fall and was on snow for almost 5 months and never once did both back wheels not hook up. Great on gravel, mud, you name it. I carved out my driveway in January through virgin woods with ice, snow, and moss and always got traction on both back wheels.


    I would think that it would make a 2 wheel drive totally bad ass! The Auburn also comes with genuine Toyota seals in their kit vs the other LSD which has after market seals.

    I spoke with the good folks at Auburn, their kit includes the differential and two bottles of additive... since I am not changing the ring & pinion, what else will I need to make the swap?

    I would think you are going to need an install kit because you are replacing the carrier, (your open diff). I am not sure. Like JTP, I re-geared as well.

    I have 4.88 gears and the Auburn LSD. I love it! It definitely makes a difference when you hit loose ground or get on the gas. It’s nice having both tires hook up at the same time. Here is what auburn recommend for the 3rd gen tundra.

    Auburn rear differential
    High performance differential limited slip
    10 1/2 12bolt
    Part number:
    5420134
    36 spline axial
    Non synthetic oil
    80-90 Weight oil with additive

    I took mine to a Toyota dealer and had them do the gears and LSD. They were a little more expensive but worth every penny.

    I had the dealer install Kazuma LSD in both my '96 T100, and '02 Tundra.

    Looking into this as well.

    I thought you had to have a special tool to remove the existing carrier bearings without destroying them or buy new bearings to press on?

    Also there is a shim kit so you'll need a stand and dial indicator to check the backlash and shim appropriately.

    So in my research parts alone is about $550 ish for the LSD unit and $220 or so for the install kit (shims and new carrier bearings).

    With shipping and new diff oil looking at about $800 in parts/consumables if you supply the labor.

    JTP,

    What "other" LSD is available that does not come with factory seals?

    How often do you have to rebuild the Auburn LSD?

    A question for anyone:

    What are the OEM part numbers for the bearings and shims mentioned above?

    I am looking for feedback from actual users of the Auburn LSD, people that have been using this particular brand of LSD for at least a few years.

    Who installed it?

    Have you experienced any issues?

    How many miles have you driven with it?

    Would you recommend it?

    I too want a LSD. I come from Fords with true LSDs and this electronic crap Toyota has given us is awful.

    I've never had the 10.5" Tundra one apart but if it's like every other Toyota I've done you only need a few tools to do it. Less if you just replace the bearings vs trying to remove them. A bearing separator and a press would be needed to remove the old bearing. Blue (or sometimes called bluing) is needed to check the contact between the teeth. A dial gauge on a magnetic base is needed to set up the back lash.

    Each bearing race is held in place on the carrier with a cap with two bolts. Make sure to mark which one came from which side, you do not want to reverse them. On the outside of each race is a giant nut that you turn to set up the backlash (I think it's like .008" but I would just measure it before removing the ring gear assembly) and the preload on the bearings. The bluing is used to check the contact between the teeth on the pinion and ring gear (I don't think it's needed since you're not going to mess with the pinion depth but it's cheap and you can check to see how healthy your gears are).

    The ring gear is pressed in place. To remove it all I have done is loosen up the bolts holding it in place so that there's about a 1/4" gap between the bolt head and the flange. With the heads of the bolts facing up and the bearings protected with a rag and it sitting on a solid surface I just tap on the bolt heads in a circle. A the ring gear comes off the heads of the bolts will come into contact with the flange. Loosen them up more and keep tapping. You might think driving a screwdriver between the ring gear and flange will work but I wouldn't do it. To put the gear onto the limited slip you can heat it up with a propane torch. I have used the bolts to pull it on without using heat. But be careful to tighten the bolts evenly. This can be difficult because you have to hold the limited slip with trying to tighten the bolts.

    .

    I would recommend it.. initially got it for the trails and snow.

    I have done 1 or 2 power brakes, on accident just to test it, nice lines. It has performed great on snow packed icy trails and hills when checking out some mountain trails. No regrets, worth the money at least for me.

    Sorry some of my replies are in the quote box.

    Any updates with this? I am looking to install an LSD in my 2WD as well. Originally we used to be able to get the "TRD LSD" as an option, I believe it was an Eaton LSD but I can't find them anymore and I don't know how these performed.
